“There was a man who sold sarsaparilla at tuppence a glass from a window in his sweet shop at the top of Cannon St Road until ten o’clock at night. One day, this man was murdered and the police found a box of money under his bed – forty or sixty thousand pounds – he had been saving all the tuppences for forty years. They bricked up the window afterwards.”
